We must find a problem in our daily life. If people go to the supermarket for food, clothing, and housing, the shopping mall usually presents plastic bags for us to buy, but there is no paper bag. Many people say that paper bags are more environmentally friendly than plastic bags, so why do shopping malls sell plastic bags instead of paper bags?
1. The first problem is the cost problem. After all, there are few paper bags on the market, and the amount of production and manufacturing of the company is also small. The price of paper bags is much higher than that of plastic bags, and the price will be relatively cost-effective due to the high industrial development level of many companies applying plastic bags. Usually, the price of a plastic handbag is 4-5 cents, while the price of a paper bag must be 4-50 cents. The price is 10 cents apart
2. Environmental pollution. Many people say that paper bags are more environmentally friendly, but we have to discuss this problem again. British Organic Chemistry Research Association has made this statistical analysis. The data shows that the production of 1 ton of plastic saves 50% of raw materials, 91% of electric energy and 75% of vapor emission compared with the production of 1 ton of paper.
According to the specific situation, the key of raw materials for plastic production and manufacturing is crude oil, and the environmental pollution caused by it is the environmental pollution in the whole process of crude oil extraction, the discharge of some organic chemical and chemical wastewater in the process of processing, and the solution of plastic products. The key to the production and manufacture of paper products is trees or grass. The key environmental pollution problem is that cutting flowers and plants destroys mountain forests, destroys some fast-growing trees of green ecology and industrial wastewater in the process of processing.
